Alps touchpad with ID 0x120A + trackpoint will not be used for mass production machines.
Touchpad 0x120A w/o trackpoint still reports it has a trackpoint, this will confuse userspace apps.

Reverts commit fcaa4a07d2a4b541e91da7a55d8b3331f96d1865, so 0x120A device is no longer a MT_CLS_WIN_8_DUAL device.

[Test Case]
Verified on the systems affected with this issue and confirmed that this solution works.

[Regression Potential]
This patch is for a single device in a specific driver.
